BOX-COVERING MACHINE.

Toall whom it may concern Beit known that I, HENRY DE SMITH, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Box-Covering Machines, of which the following is mgs. This invention relates to that class of maa specification.

rier for the box-form on which the boxes tobe covered are placed, a cut-0E for severing the covering strip into proper lengths for the boxes to be covered, and mechanism for actuating the box-form carrier andthe cut-off. In these machines the box-form carrier is usually adjustable in order to permit of adjusting the position of the boxform relative to the cut-oifaccording to the size and form of the box being covered, and also to permit of adjusting the height and general location of the box-form according to the convenience of the operator. To provide for such adjustment of the box-form carrier the driving connections between the same and the driving shaft are also adjustable, and it is to such feature of the machine, that is, the adjustable driving connections between the box-form carrier and the driving shaft that my present invention more particularly relates.

The object of my invention is to provide a box-covering machine having a new and improved operating mechanism for the rotary box-form carrier. c r

In carrying the invention into effect I preferably provide a pivotally and slidably supported frame or holder on which, is mounted the rotary box-form carrier and a drive connection between said carrier and the driving shaft, the said drive connection including a belt which is mounted on said holder in a manner to be bodily movable therewith and to be maintained thereby in operative connection with the driving shaft upon adjustment of the box-form carrier.

Referring now to the accompanying drawings forming part of this specification, Figure 1 is a side elevation, partly broken .aWay, of the front end of a box-covering machine embodying my invention. Fig. 2 is a par- Specification of Letters Patent.

tial front end elevation of the same. Fig. 3 is an enlarged sectional detail, taken on the line 83 of Fig. 1. Fig. 4 is an enlarged sectional detail, taken on the line 44 of Fig. 1.

Like reference characters indicate like parts in the different figures of the draw- A indicates a portion of the main frame of a box-covering machine, and B a secondary frame removably secured to said main frame and having suitably mounted thereon the other main elements of the machine, including thecut-off, indicated generally by C, the box-form carrier, indicated generally by D, the holder for the box-form carrier, indicated generally by E, and other associated and cooperating parts to be referred to. The association "of the cut-off and boxform carrier and their supporting and operating elements in the form of an attachment for removable connection with the main frame of themachine, as herein disclosed,'is made the subject-matter of Patent No. 1,037,154, of August 27, 1912.

The holder E for the box-form carrier is shown in the present case as being in the form of a skeleton frame composed of two parallel rods 2, 2, connected at their opposite ends by cross-heads 3, 3. The holder as thus formed is slidably mounted on a support 4 by means of its rods 2, 2, extending through openings or seats in two pairs of bosses 5'55 5, on said support, and the said support in turn is pivotally mounted on a boss or stud 6 on the frame B, as clearly shown in Fig. 3. In this manner the holder E is rendered capable of the desired slidable and pivotal adjustments for the purpose of adjusting the position of the supported boxform carrier relative to the cut-off and otherwise, as indicated by the full' and dotted line positions shown in Fig. 1. The said adjustable holder may be secured in stationary adjusted, position by any suitable means, it being preferable to provide a means that is operative at one operation to effect the securing or locking of the holder with respect to both its pivotal and sliding adjustments. The means provided in the present case for such purpose comprises a bolt 8 mounted on the pivotal support 4 with one end extending through a segmental or arc-sha ed slot 9 in the frame B and having a hea or nut 10 for engagement with said frame, and its other end carrying a retaining member 11. for clamping engagement with the rods 2, 2, of the holder E, and a locking member in the form of a lever-nut 12. Upon the loosening or tightening of this member 12, it will be understood that the holder and its support will be either free for adjustment or locked in adjusted position.

The box-form carrier, which is of usual construction, is operatively connected with a shaft 14 journaled in the front end of the holder E, which said shaft is in turn opera tively connected with a driving shaft 15 through the medium of a drive connection,

here shown as a chain-and-sprocket connec-' tion, the chain being indicated at 16, and the two sprockets, secured to the said shafts, being indicated at 17 and 18. The axis of the said driving shaft 15 and that of the holder E in its movementabout its pivot, are coincident, and for such reason any adjustment of the holder about its said pivot does not disturb the relation between the said carrier-shaft 15 as to their distance apart, but any sliding adjustment of the holder does disturb suchrelation between the shafts and for suchreason it is desirable that some provision be made to maintain proper operative relation of the drive belt or chain 16 with said shafts and their sprockets upon such adjustment of the holder. This is accomplished in the present case by supporting the chain 16 on the holder E in a manner whereby it will be bodily movable therewith and at the same time maintained in constant operative relation with the driving sprocket 18, such supportof the chain being effected by mounting a sprocket 19 on said holder at its inner end for engaging the loop end of said chain opposite that engaged by the sprocket 17 on the carrier-shaft and so supporting the chain independent of support by the driving sprocket. As a means to take up slack in the chain and assure its positive engagement with the said driving sprocket, two idler sprockets 20, 20, are preferably mounted on the support 4 in position for engagement with the chain at opposite sides of the driving sprocket as shown.

The'driving shaft 15 may be operated in any suitable manner, the same in the present case being shown as having connection through gearing '21 with a shaft 22, which latter is adapted to be driven from a driving pulley 23 through a clutch connection 24 controlled from a foot lever 25 through suitable connections, such as indicated at 26, 27 and 28.
